The JCenter Maven repository is no longer accepting submissions of Maven
artifacts since 31st March 2021.  Ensure that the project is configured
to search in repositories with the latest versions of its dependencies.

!!! Tip
   This lint check has an associated quickfix available in the IDE.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
build.gradle:7:Warning: JCenter Maven repository is no longer receiving
updates: newer library versions may be available elsewhere
[JcenterRepositoryObsolete]
    jcenter()
    ---------
build.gradle:14:Warning: JCenter Maven repository is no longer receiving
updates: newer library versions may be available elsewhere
[JcenterRepositoryObsolete]
    jcenter()
    ---------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is the source file referenced above:

`build.gradle`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers
buildscript {
    ext {
        versions = [kotlin: '1.4.20']
    }
    repositories {
        google()
        jcenter()
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test
found for this lint check, `GradleDetector.testJCenterObsolete`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Using a suppression comment like this on the line above:

  ```kt
  //noinspection JcenterRepositoryObsolete
  problematicStatement()
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="JcenterRepositoryObsolete" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'JcenterRepositoryObsolete'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore JcenterRepositoryObsolete ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
